Subject: [9fans] Pentium F00F bug?
Date: Mon, 9 Oct 2000 09:05:45 GMT

Hi,

I recently installed plan9 on a Pentium 75 Mhz machine, w/ 64 Mb RAM, Cirrus
Logic CLGD-5430 (pci) video card and Intel EtherExpress Pro/100B ethernet
adapter.  I had to explicitly limit memory size with *maxmem statement in
plan9.ini and add a lib/vgadb entry for rio.  Otherwise, the installation
proceeded normally.

I have been playing around with this box with much gusto.  However, every
once in a while, it freezes and has to be power-cycled.  I have noticed this
happens when there is sustained network activity for a few hours, like a
remote ping.  I am not sure if there is a co-relation though, as this might
have to do with the F00F bug in the Pentium processor on this machine.  At
the moment, I don't have spare hardware to isolate the problem, so I am
hoping someone here can help me debug it.

best regards,
vipul.
